UNITED STATES PATENT IM PROVEM ENT IN- KNITTING-MACHINE.

Specification il'n'ming part of Letters Patent No. 107,230,datedheptmnlwr l3, 1870.

To all whom it may concern:

Be it known that I, OWEN DAvrs, of New Lebanon, in the county ofSullivan and State of Indiana, have invented new and usefulIniprovements in Knitting-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the accompanyingdrawing, making a part of this specification, in which- Figure l is atop view of lever, frame, and connecting-rod as attached to the machine.Fig. 2 is a front elevation of fender. Fig. 3

'is a section of the fender, taken in the direction of the line :0 w ofFig. 2. Fig. 4 is a side view of threader-hook. Fig. 5 is a side view ofthe lever, frame, and clamp.

Like letters in the different figures of the drawingindicnte like partsof theim'cntion.

Nature.

My invention relates to improvements in the Lainb knitting machine; andconsists, first, in operating the machine by'a lever instead of a crank,the lever being provided with a separate clamp, by means of which it isattached to the table at the right end of the machine, and having aconnecting-rod: which is' handling it, and the lower part being made vsufficiently large to extend down between the inclined jaws or plates,so as to protect the fabric from the heel-comb during the process ofknitting the heel.

A is a lever, having a handle, b, and B is a frame, to which the leveris attached by the pivot-bolt c. The frame 13 is made in the shape of asegment of a cir'cle,'and is provided with stops at d,,against which theback end of the lever A strikes as soon as the carriagecamsare shifted,to prevent the concussion .C is a staystrap, secured at the front end bythe pivotbolt 0, which passes through a hole therein.) 1

and extends over the top and down the back of theframe, forming thestirrup e, which is fastened by a screw to the top of the table, as

shown in Figs. 1 and 5. .D is the clam'p,,provided with set-screw f, bymeans of which the frame B is fastened to the, table or shelf. E

is a connectingmd, attached to the lever A 1 i 7 at or near the middlethereof, and to the car-Q riage U, by thesame pivot-bolt whichconnectsand holds theconnecting-rod of the Lamb} machine. F is a'fender, madewith a cape or; flange-G, which is provided with slots s,,s'uf-';ficiently large and the proper distance apart,

ass

to readily admit theJjack-wires G to through them, as seen 'in Figs. 1and 2. 'lhe two projecting handles it h on the top.

are for the convenience of the operator in- Lamb-machine hookrequiresfrom six to twelve motions of the hand.

Operation.

The lever-clamp should be attached to the same tableor shelf to whichthe machine is attached, at the right-hand end of the machine, and themovement of the lever A to the right and left operates the slidingcarriage G, the

back end of the lever striking againstthe.

stops (l d as soon as the carriage-cams are shifted, thus preventin gthej amming of themachine. The lower end of the fender is placed betweenthe needle-plates, with the cape G to the front, which is pressed downover the front row of jack-wires, G, which project through the slots 8,as seen in'Figs. 1 and 2,. and is kept in that position during.theprocess of knitting the heel, thus efl'ectnally protecting the fabricfrom the heel-comb. .When the heel is completed the fender is lifted upand removed by thehandles h h.

In using "the' threader, the shorthook c is passed up through the eye ofthe yarn-carrier, and catches the yarn and draws it down through theeye.

What I claim is- 1. The combination of the lever A, connecting-rod E,frame B, stops d d, and clamp D f, all constructed and arrangedsubstantially as described, and adapted to operate the sliding frame ofa knitting-machine, in the manner set forth. i

2. The fender 1*, provided with the cape 0r flange G and slots s, andadapted to be ap ()WEi DAVIS. Witnesses:
